To all whom it may concern.

Be it known that I, 'HARRYEDWARD EWALT, a citizen of the United States, and

. Referring to the drawings a pa er supporting table is indicated at A an isprovided with acabinet ortion 12 formed by walls- 10 and 11 and-a ottom 11'. The wall indicated at 10 is hingedly supported as at -13 affording access to the interior 12 of the cabinet. The top wall of the cabinet is after. The wall portion indicated at '16 extends upwardly from the top 13 and is "indicated at 13 and comprises members 14 of non-conductive material supporting a metal plate 14' of conductive material the purpose of which will be described-herein cesses 21 formed therein table which carries the elements for treatin terminating at their upper ends I wall of this structure indicated at 24 has an extended portion 25 carrying oppositely extending roller members 26 which engage the grooves l8, and which are secured in a suitable manner to the portions 25 by supports 25.

It will be noted that when the roller members enter the grooves 19 the structure B will be held in the position indicated by dotted lines, Fig. 4, therefore allowing free access over the top 13.

The above description is the preferred form construction of the supporting table embodied in the invention and it is this ing the paper, which elements will be described in such language as will be best understood by those skilled in the art.

Within the cabinet 12, in the interior 12 thereof I mount in any suitable manner a high frequency transformer 27 of any approved type, said transformer being illustrated diagrammatically. This transformer is controlled by a nheostat 28 of any approved type and the current flowing through the rheostat .is controlled by a switch 29 of any approved type, both switch and rheo stat being mounted on the wall 11 as shown in Fig. 1.

,Referring to Fig. 1, a sight hole. is -indi-' cated at 30 formed in one of the side walls 20 permitting observation of a spark gap 31 which is mounted with the interior 32 of the structure B. This spark gap comprises a stationary pole 33 carried by the metal plate 23, and an adjustable pole 34 mounted in 'a suitable manner on the plate 22, and adjustably controlled by an operating knob 32' carried by a shaft 33 connected to pole 34.

These elements above described include the'elements for electrically treating paper.

and are connected in circuit together in the manner illustrated in Fig. 6, a description of which will now be outlined.

Fig. 6 a diagrammatical view of the circuit, connection embodied in the=invention and in this illustration the primary and secondary sectionsof the transformer 27' are indicated .at- 35 and 36 respectively. *The primary section 35 is connected in circuit with one side of the switch 29 and the rheo- -so the high stat 28 by conductor wires 37 and 38 respectively, the other side of the switch being connected in circuit with a suitable electrical current 39 by conductor wires 39. It will be noted that when the switch is closed the current will flow through the rheostat to the primary section of the transformer.

Oneendof the Winding of the secondary section is connected in circuit with the plate 14 by a conductor wire 40, the other end of the secondary section winding being connected in circuit with a suitable ground 41, by a conductor wire 42. This ground 41 is also connected in circuit with plate 22 by a conductor wire,43.

The induction of the current from the primary section to the secondary section causes a current to fiow through conductor wire 40 to plate 14", and induced to plate 23 through space 9, which will accommodate a roll or stack of paper for purposes set forth herein, by spark gap 31 to plate 22 and thence to ground 41 through conductor 43 also to which conductor wire 42 terminates, completing the circuit of the secondary section 36. i

As herein stated'the principal object of the invcntionis to treat or season paper in any form, by a high frequency current, to best mature the paper for its various commercial uses and the operation of the invention to accomplish these various objects will now be explained.

In placing the paper in space S) on the supporting table the structure l5 is elevated until the paper is n place and then this structure is lowered as to rest upon the paper. In such position it is apparent that the metal plates of the structure ii and metal plate 14 are in spaced relation providing the space 9 and that it is necessary that the high frequency current flowing from the secondary section of the transformer to the plate 14 traverse this space to pass through the plates 22 and 23 to ground 41. In doing frequency current 1 passes through the paper and as the current generates heat from the surrounding atmosphere moisture in the paper will be removed therefrom.

Ordinarily printing houses store printing paper in a store room having a temperature less than the room where the paper is put through the press. This being the case it is obvious that the paper coming into contact with a warm atn'iosphere and warm machinery parts, will have a tendency to curl, warp, or s'hrinlrand the paper being in a cool state or condition the ink received thereby will not dry readily after the paper leaves the press. The same defects occur when the paper is put through a cutting machine.

By the provision of a device as herein described the paper beingelectrically treated above and many otherdefects commonly met with in the paper and printing arts. 5 I

In the operation of the device herein described the paper to be treated isposltiohed between the plates 14 and 23 in space 9 with structure B supported by-the paper. The switch is then closed allowing the current to. flow to the primary section of the transformer from the rheostat,the latter beingadjusted to obtain the degree of current desired;

The current from the primary section leaves the transformer through the secondary section and flows to the plate 14'. From here the current at high frequency .1s at+ tracted by the spark gap and jumps through and 23 throughthe space 9-and continues on to the ground. The current in traversing the space 9 passes through and round ,the paper arranged in said space. In doing this, current heats the atmosphere as well as the paper and in heating the atmosphere an airmovement is created and carries off the moisture contained in the paper. The heat from the current removes the statical electricity and magnetic attraction from the paper. After treating the paper it will be found that the paper will take the link without blurring and as 7 known by those skilled the temperature of the paper has been raised the ink will more readily dry permitting the sheets of paper to be stacked in pile form.

By regulatingthe degree of current traversing the space between the plates the temperature of the paper can be raised to substantially the same temperature of the cutting or press room.

.From the above description it is apparent that I accomplish the "numerous objects of the invention, removing such defects well in the paper'and printing arts. 1 In Fig. 5,1 have shown a modified form of construction to treat paper in roll form;

In this construction I provide two segments 50 and 5-1 shaped to fit one above the roll of paper and one below the aper. A block f 52 is mou'nteil between the p ates 14? and. 23. .This block includes plates 53 and 54 in contact: with plates 14 and, 23 respectively.

Lead wires 55-and 56 connect the segments "with .plates50- and 51.1 .The operation of "this 'form is substantially the sameas the preferred. form .with -the exception that the stated. lVhile I have f'preferred form of construction for carrying invention into efi'ect, thisis' capable of f'va'riation and. modification" without departcurrent traverses the 'roll of paper between the segments 50 and 51'. In this way "I am I able to season paper in .roll forms as well as paper in sheet forriis for purposes herein illustrated and described the modifications as come within the scope of the appended claims.
